Do these mount at the factory rocker points without drilling?

Yes, these are designed to use factory mounting locations along the rocker line. No drilling or frame modification needed — bolt them to the existing attachment points on your vehicle.

Can I install these myself with basic hand tools?

Designed for DIY installation with basic hand tools and a jack. You'll need to safely lift the vehicle, position the bars, and fasten at the factory points. If you're not comfortable working under the vehicle, have a shop handle it.

Do I need to paint these before installation?

The black finish is ready to mount as-is. If you want a custom color or gloss level, prep and paint before bolting them down — it's easier to finish them off the vehicle than after install.
